To all whom it may concern:

Be it known that I, RUDOLPH C. KRUscI-IKE, citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Mining-Headlights, of which the following is specification, reference being had therein to the accompanying drawing.

This invention relates to miners lamps, and the principal object of the invention is to provide a lamp which may be conveniently carried and which will be safe to use.

Another object of the invention is to provide a lamp in which a reflector or a chimney device which carries a reflector may be selectively used.

Another object of the invention is to provide an improved type of bracket for connecting the globe or reflector with the hat of the miner.

With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a view of the lamp chimney and supporting bracket, the chimney being shown partially in side elevation and partially in vertical'section. Fig. '2 is a vertical section through the carbid generator. Fig. 3 is a side elevation of the supporting bracket and reflector. Fig. 4 is a section along the line 44, in Fig. 3. Fig. 5 is a section along the line 55, in Fig. 3. Fig. 6 is a perspective view of the bracket which is connected with the cap of the miner. Fig. 7 is a view of the blank from which the bracket is formed,

This invention comprises a generator shown in Fig. 2 and is adapted to be connected with the belt or some other convenient place upon the body. The generator of the threaded portion 35.

bid receptacle to permit the gas generated in this receptacle to pass into the upper portionof the chamber 13 and from this cham her out through the pipe 20 into the rubber pipe 21 which leads to the lamp mounted upon the miners cap. A valve stem 22 controls the flow of water through the pipe 19 and is provided with a threaded upper end portion 23 to permit the stem to be held 1n an adjusted position. A hook 24 is provided so that the generator may be conveniently connected with the belt. A bracket shown in Fig. 6 is connected with the cap of the miner and is formed from the blank shown in Fig. 7 This blank comprises the body portion 25 having the small ears 26 by means of which the bracket may be sewed to the cap, and thus firmly held in place, and with the wings 27 which are folded along the dotted lines 28 to assume the position shown in Fig. 6. The body portion is folded along the dotted line 29 to form a hook 30 by means of which the bracket may be connected with the hat band or with any other suitable supporting plate which may be secured to the hat. This plate does not form part of this invention so it is not considered necessary to illustrate the same. The side wings 27 are provided witl openings 31 and are provided with ribs 32 as clearly shown in Fig. 6. These ribs are provided to permit the angle of the reflector or lamp to be regulated, and the openings 31 are provided to permit a coupling 33 at the end of the pipe 21 to pass through the side wings for a purpose which will be hereinafter brought out.

A tube 34 is provided with a threaded portion 35 and with a collar 36 at the base The tube beneath the collar 36 is reduced somewhat and is positioned between the wings 27 with the coupling 33 passing through the inner end portion of the tube. It will, thus be seen that this coupling pivotally mounts the tube and also permits the gas in the pipe 21 to pass into the tube 34.

In Fig. 1 there has been shown a lamp which comprises a chimney 37 having its lower end portion removably connected with a metallic base 38 which is removably connected with the tube 34 having its collar 39 threaded upon the threaded portion 35 of the tube 34. A reflector 40 is carried by a supporting bar 41 and is positioned behind the chimney so that the light will be thrown in front of the miner. It is, of course, obvious that the usual tip 42 may be applied in the end of the tube 34: so that the gas may be burned. When this form is used the lamp is preferably held in a vertical position, but if desired it may be tilted forwardly for loosening the coupling 33 and after the tube 34 is turned to the desired angle the coupling may be tightened to draw the wings 27 close together again.

In Fig. 3 the lamp shown in Fig. 1 has been done away with and a reflector 43 is mounted upon the threaded portion 35 of the tube 34 by having its collar 44 threaded upon this threaded portion 35. WVith this form the chimney has been done away with entirely and it will, therefore, be seen that when this form is used a great deal of weight will be dispensed with and, therefore, there will be less tendency to tear the bracket loose from the hat. If desired the usual wire screen may be placed across the reflector and at the top and bottom of the chimney, thus preventing any danger of eX- plosion. This reflector may be angularly adjusted by loosening the coupling and after the tube is turned to the desired angle the coupling may be tightened in the adjusted position. When using this lamp the generator is first charged in the usual manner and will generate enough gas to last for the entire time the miner expects to stay in the mine. The lamp is lighted before the miner descends in the car and, therefore, it is not necessary for the miner to light the lamp when in the mine since the carbid lamp does not readily go out and, therefore, the danger of an explosion caused by lighting the lamp in the mine is done away with. The generator is connected with the belt and the bracket which carries the lamp or reflector is connected with the cap. After the miner reaches the bottom of the mine he may adjust the tube to throw the light in the direction that he wishes, thereby causing the light to be thrown directly on the work he is doing. After the miner returns to the surface the lamp is removed and can then be readily recharged. It should also be noted that if desired the miner may carry the reflector in his'pocket so that if the chimney were to break he could remove the base 38 from the tube and place the reflector 43 in position.

Having thus described the invention what is claimed as new, is V 1. A device of the character described comprising a bracket having a rear hook provided with side ears, and said bracket having forwardly projecting side wings, a burner pivotally connected to the wings, and a reflector carried by the burner.

2. A device of the character described comprising a bracket formed of a single length of material shaped to provide a front body and a rear hook, said hooks being provided with perforated side ears, the body having wings projecting forwardly from the lower ends of its longitudinal edges, said wings being provided with radial seats and central transverse openings, a coupling extending through said seats, and. a burner tube selectively held to said seats by said coupling.

3. A device of the character described comp-rising a. bracket, a burner pivotally connected thereto and provided with a threaded portion and a collar, a chimney support being provided with a chimney holding flange, and a reflector carried by the flange.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.
